Georgia Republican Senate candidate Herschel Walker has a message for Americans who say insulin is too expensive and should be regulated by the federal government: If you’d simply “eat right,” you wouldn’t need insulin in the first place.

During a debate between Walker and Democratic Georgia Sen. Raphael Warnock on Friday evening, the subject of the U.S. economy and inflation came up, to which Warnock noted that he had worked to help pass legislation — the Inflation Reduction Act — that lowered the cost of prescription drugs, including a cap of $35 on monthly insulin costs.

In response, Walker claimed that the Inflation Reduction Act hadn’t actually reduced inflation. And then he said anyone who has a need for insulin needs to think of eating better as a solution to their condition.

“I believe in reducing insulin but at the same time, you gotta eat right. I know many people that’s on insulin. Unless you’re eating right, insulin is doing you no good. So you have to get food prices down and you gotta get gas down so you can go get insulin.”

While it’s true that eating healthy can indeed reduce a person’s risk of contracting Type 2 diabetes, diet does nothing to prevent or cure Type 1, which results when the pancreas cannot produce insulin at all and is therefore in need of injecting the substance to keep regulate their blood sugar. Otherwise, the person will die.

Twitter users also corrected Walker for his remarks on eating better to control diabetes.
